DEVICE FOR SHAPING SCRAPERS.

Specification of Letters Patent.

Patented Nov. 22, 1910.

`Application filed November 3, 1908. Serial No. 460,856.

To all whom it may concern:

Be it known that I, WILLIAM B. CAMERON, a citizen of the United States,residing at Piedmont, in the county of Calhoun and State of Alabama,have invented new and useful Improvements in Devices for ShapingScrapers, of which the following is a specification. 1

This invention relates to devices for shaping agricultural Scrapers, andone of the principal objects of the same is to provide a hand-operabletool for shaping` or setting earth Scrapers for agricultural purposes,said device comprising a base having the required contour and a leverprovided with a pivoted former.

Another object of the invention is to provide a hand tool which willquickly shape and set a land scraper blade and which will form a bolthole therein for connecting the scraper to a standard.

Land Scrapers after they have been used a certain length of time becomebent, misshapen and dull. It is the purpose of my invention to take suchScrapers and place them in position between the anvil and the lever forgiving them the required set and shape.

These and other objects may be attained by means of the constructionillustrated in the accompanying drawing, in which,-

Figure l is a perspective view of a tool or device made in accordancewith my invention. Fig. 2 is a vertical sectional view, showing thelever thrown upward in position to place a scraper in position to beset. Fig. 3 is a perspective view of one of the scrapers for which mydevice is adapted to shape a seat.

Referring to the drawing, the numeral 1 designates a work stand uponwhich the device is adapted to be secured or upon which it is supported.The base 2 is provided with divergent anvil members 3, the uppersurfaces of which are inclined at the required angle to form theundersurface of the scraper. Guides I extend upward from the anvilmembers 3, said guides being disposed at the inner edges and near thejunction of the two members 3. An inclined surface 5 for shaping thepoint of the scraper is provided with an upwardly extending punch stud6. Pivotally connected to an upwardly extending standard 7 provided withspaced arms 8 is a lever socket 9, said socket having a recess 10 in theunderside thereof, .and pivotally mounted in said recess is a link 11,the outer end of which is pivotally connected, as at 12, to a formerblock 18, said former block having oppositely disposed members 14k and aconnecting cross bar 15, the latter being provided with a recess 16 forthe punch stud 6. A lever handle 17 is detachably connected to thesocket 9.

It will be obvious that by reason of the length of the link 11 and itsparticular pivotal connection with the former block 13 and in the leversocket 9, the said lever on downwardly depressing the same will contactwith the former block so as to relieve the strain upon the link 11, thustransferring the strain from the lever directly to the former block.

The operation of my invention may be briefly described as follows: Abent or mis shapen scraper blade may be placed upon the anvil member 3,and by bringing the lever 17 down the scraper is set and shaped to therequired contour. New scraper blades may be readily formed on the deviceby placing the blanks in position and operating the lever 17 to pressthe blank into proper shape and to form a bolt hole therein near thepoint.

From the foregoing it will be obvious that my invention is of simpleconstruction, can be manufactured at low cost, can be operated toquickly shape and set scraper blades, and is strong, durable andefficient for its purpose.

I claim The herein described device, comprising a V-shaped base havingupper concaved faces, an inclined block rising centrally from said baseand having a vertically central punch stud, a standard on the said baseand having a bifurcated upper end, a lever pivoted at one end to thesaid standard in the bifurcation, a former having forwardly divergingextensions spaced from each other, a link pivoted to the lever andformer whereby on depressing the lever the latter will bear upon theformer, the said former being provided with a recess correspondinglyspaeed to the said punch stud for receiving in presence o two Witnesses.the same, and upstanding lugs spaced from his eeohV other on? the saidbase and Yhaving WILLIAM B'mkCAMBRON 5 beyeled inner faces engaged bythe eXten- In testmon whereof I affix lny signature v Witnesses: slonsfor guldlng the former to lts seat 1n J.
